SHAFT BEARING'. Y

.To alle/7mm{1i-may concern.:

Be it known that l, JOHN l. Gouril. a citizen ot the United States,residing in lutlalo7 in the county ot lrie and State oit New York. haveinvented new and useful lmprovenients inV Shaft Bearings. ot which thefollowing is a specification.

rlhis invention rel; 'es to the class ot seltoiling shaft hearings orournal boxes which are provided in their bottom with an oil well orreservoir into which. dips collar secured to the sha tt, so as toelevate the oil to the top ot the latter, an oil-detlecting saddle beingmounted on the shatt and the shaft seat ot' the bearing beine' providedat its ends with channels or passages through which the surplus oilreturns into the reservoir.

One ot the objects ot the invention is to improve the construction ofthe oil-deflecting saddle with a view ot effecting a quiet flow ot' oilover the top of the sha'tt and preventing its splashing and escaping atthe top of the bearing box.

A further object is to provide the bearing with improved means torpreventingl lealtage of oil at its ends and through the joint betweenthe upper and lower sections ot the bearing-box.

In the accompanying drawings: Figure 1 is a central longitudinal sectionot t-he bearing. with the shaft shown in dotted lines. Figure 2 is a topplan view o't the lower section ot the bearing. Figures 3 and 4- aretransverse sections on the Correspondinglvv numbered lines in Fig. 1.Figure 5 is a perspective vie-w ot the saddle.

Similar characters ot reference refer to like parts throughout theseveral views.

The bearing-box may be ot any approprivate construction but preferablyconsists of a lower section 10 and an upper section 11, the lowersection being provided with a retaining rim 12 within which the uppersec-tion tits.

Formed in the lower section is a semicylindrical shaft-seat 13 under theopposite ends ot which are arranged oil wells or reservoirs 14 connectedby a channel 15 in the central portion ot said bearing section. Theshaft-seat ot the bearing may be provided with the usual lining 16 ofbabbit or similar material.

19 tornied on the shaft-seat l?) and its lining and dip into the oil inthe reservoir 14, in a well known manner. rThe upper poirtions ot thesecollars extend through similar slots in the top oit the lining 16 andinto filling-openings 2O having removable covers 21.

Adjacent to the ends ot the shaft-seat. the bearing box has annular oilgrooves 22 which open into the correspendingl reservoirs 14 :t'orreturning any surplus oil thereto. Projecting' troni each end ot saidshattseat are two or more substantially dove-- tailed lugs oroil-scrapers 23 which are prei'- erably located on opposite sides ot'the ceuter line ot the bearing and adapted to intercept and scrape fromthe underside ot' the shaft any oil which may creep outwardly beyond theends ot the shaft-seat 18. the oil thus removed trom the shaft drippingover the lateral edges ot the Scrapers into the reservoir. The upper orbearingl faces oit these scrapers are provided with transverse grooves24 which extend lrom edge to edge thereot' and serves to prevent the oilfrom leaking at the outer ends oi the bearing, said grooves compellinglthe oil to ilow into the reservoirs 1t These grooves especially servetheir purpose when the oil becomes thick after being in the bearing torsome time.

rlhe lower bearing section l0 is provided on opposite sides between therim 12 and the upper edge of the lining` 1G with longitudinaloil-receiving grooves or channels 25 which extend throughout the lengthof the shaft-seat 13. as shown in Fig. 2. These grooves receive thesurplus oil splashed upwardly from the reservoir and conduct it backinto the same through the slots 19 and grooves 22. ln addition to thisfunction, these grooves do away with the usual leather packing betweenthe upper and lower sections ot the bearing-box, thus etecting animportant saving` in material and in the time required to pack the box.

It will be noted that the rim 12 on the lower section 10 extends asuitable distance above the joint between both box-sections, thuseffectively guarding against leakage of the oil over said rim.

Arranged within the lling openings 2O and the straddling the adjacentportions of the shaft-collars 18 are the saddles or oildetiectors 26.Each ot these saddles consists of a plate somewhat narrower than theAreturn into the reservoir.

lilling opening, having in its lower edge a central notch 2T whichreceives the coinpanion collar and snugly fits the saine to preventleakage of oil between theseparts. The upper portion ofthis notchpreferably extends above the corresponding face of the shaft-collar, asshown in Figs. 1 and 3, to forin a relief passage 28 which allows anyexcess oil to pass forwardly through it and In the drawings, tlreupperportion of said notch is tapered upwardly, the saine being shown in theshape of an inverted V, but it may be of any other appropriate shape. Toretard the How of oil through the relief passage, its side walls aretapered rearwardly, as shown in Figi. Y n Y The edge of the saddle-notchmay be provided with kthe customary flange 29 which projects beyond theface of the saddle and shaft 17. During the rotation of the latter, thesaddle rests against the rear wall of the Vlilling opening 20 and thefeet 3() prevent the saddle from tilting forwardly. The relief passage28 is located below said wall and within the main chamber of thebearingbox, as shown in Fig. l.

Above the relief passage, the saddle has an opening or cavity 3l whichpreferably `extends through theV saddle-plate and is closed at the backby the rear wall. of the filling-opening 20. This cavity is formedpartly in a boss or upward extension 32 of the saddle-flange 29, and inits preferred foi-in it is tapered rearwardly, as shown. By thisconstruction and arrangement, soine of elevated oil enters the opening31 and gently Hows out of it again, preventing it from splashing out ofthe top of the bearing-box.

A handle 3S may be provided at the top of the saddle for convenientlywithdrawing it from the filling-opening 20, when desired.
